manna-nalin To all whom it may concern: ,-Be it known that I, CHRISTIANWIN KLER, `a citizen of the United States, residing at Portland, in thecounty of Multnomah and State'of Oregon, have invented a new and usefulPlaner-Head, of which the following is a specification.

It is the object of the present invention i to provide an improvedconstruction of planer head and more specifically to provide 1animproved tool holding means for such a'hea the means beingso'oonstructed as to support, upon a single head, two planing tools, thecutting edges of the tools being presented in opposite directions anddie tools being so supported than when the bed of the planer is moved inone direction, one -tool will perform its planing function 'and when thesaid bed is moved in the opposite or return f direction, the other lanertool will perform its planing function. Thus, the invention provides'forthe performance, in a planing machine, of the planing operation whetherthe bed of the machine is moved forwardly or backwardly.

One of the aims of the present invention is to provide, in a planer headembodying- .holding means for two planing tools or bits, means wherebythe said holding meansl may be adjusted relatively both as regards depthof cut and alinement in' the direction, of

' travel of the bed.

With the above and other objects in view,

the invention consists in the general construction and arrangement ofparts shown in the accompanying drawings, in which,

Figure 1 is a view partly in side elevation and 'partly in verticalsection through a planer head constructed in accordance withl thepresent invention. Fig. Q is a view infront .elevation of the planerAhead'. j

In the drawings, the numeral 5 indicates the planer head proper, thisplaner head being mounted in the frame of the planer above the bedthereof in the ordinary manner. Secured by means of vsuitable bolts 6 orother similar devices, to the front face of` Specification of LettersPatent. Patented June 13 SLL VApplication led August 18, 1910. SerialNo. 577,894. l

hanger pin 9 is a tool holder indicated. by the numeral 10. rI"he pin 9passes through the upper end of the tool holder 10 and the upper forwardedge or corner of this helder 10 is rounded as at 11 so that the-holdermay have pivotal swinging movement upon the pin 9 in the direction ofthe planer head 5. It will however be noticed that the forward side ofthe holder 10 rest-s fiat against the rear face of the connectingportion 8 of the head block so that swinging movement of the tool holder10 in a forward direction is limited. The tool held by this holder isindicated by the numeral l12 and is of any ordinary or specialv form andis se# cured in place by a vset screw 13 engaged through the ends of abail 14 fitted about the lower endof the tool holder 1Q and the tool 12therein.

For a purpose to be presently described, the connecting portion S of thehead block 7 is formed in its lower edge with a groove 15 and in itsforward face, in a line transn versely substantially midway between itsupper and lower edges, with a groove 16. horizontal slide having itsbody indicated by the numeral 17 is formed at its lower edge andprojecting from its rear face, with af flange 18 having an upstandingrib 19 litting -slidably in the groove 16 and the rear face of thesaidbody 17 is further formed with a boss 20 located at the middle of thesaid face and formed with a threaded bore indicated by the numeral 21.'This boss 20 projects into the groove 16 and is free'to move therein. Aflange 22 projects from the said rear face of the body 17 at the-upperedge thereof and projects over the upper edge of the connecting portion8 of the head block 7 and it will be readily understood that by so'disposing the horizontal slide 'upon the head lblock, it may be adjustedtransversely therealong. In order that this ladjustment may be readilyaccomplished,

ice

is threaded through the boss 20. The screw 23 is held against movementlongitudinally with; respect to the head block through the medium of asuitable collar 2/1- secured upon each of its ends and one end of thescrew is,

squared as at 25 for the engagement therewith of a` wrench or othersimilar tool by means of which it may be rotated to feed the boss ,20and consequently the body 17 of the horizontal slide, -inonfe directionor the other transversely along the 'head block 7. In order Ato hold thehorizontal slide 17 at points of adjustment upon the head block,- Ithereis provided a set screw 26 which is threaded through theflan e 22 andbears against the upper edge o the connecting portion 8 of the said headblock.

vThe horizontal slide 17 includes spaced vcheek portions whichareindicated by the numeral 27 and each of these cheek portions is formedwith a slot indicated by the numeral 28. A slide block 29 is fitted forvertical sliding ad'ustment in each slot 28 and vfixed. at its .en s inthe slide block 29 is a hanger pin indicated by the numeralI 30. Thebifurcated upper ends of avtool holder 31 are pivotally connected withthe hanger pin 30 and .between the furcations of the said holder at itssaid upper ends there is fitted v a collar 32 "fxedly carried at thelower end of thehorizontal slide.v

From the foregoing it will be readily I understood that by rotating thehand wheel spondingly adjusted. It will further be ob- 34;, the stem 33may-be adjusted up or down and that' the tool holder 31 will becorreserved from an inspection of the drawings that while the toolholder 31 may swing forwardly upon the hanger pin 3() as a pivot, itsupper rear corner being rounded as at 36, it is held against rearwardswinging i Inovemen` by reason of the fact that it abuts at its rearface .against the forward face lof the horizontal slide 17. A tool 37corresponding to the tool 12 is held by a ,holder suspended therefrom.

hailv 38 and set screw 39 upon the'tool holder 31 inthe same manner asis the tool 12, upon the holder 10 and the cutting edge lof the tool 37is presented in a forward direction whereas that of the tool" 12 ispresented in a rearward direction. As a result., when the bed of theplaner (notfshown) is moving rearwardly, the tool 37 will act upon thework upon the bed whereas when the headis moving forwardly, the tool 12will act over the tool 37 and its holder 31 may be adi justed verticallyby rotating the hand wheel 34 in one direction or the other. Also, thetool holder 31 may be adjusted laterally with respect to the tool holder10 by rotating the adjusting screw 23. i

What is claimed is:-

In a machine of the class described, a head block, a hanger pin mountedin the head block, a tool holder suspended from the hanger pin, ahorizontal slide mounted upon the head block for adjustment transverselythereof, a hanger pin mounted in the horizontal slide, means for'adjustingihe'last mentioned hanger pin vertically, and a tool `Intestimony that I claim the foregoing as my own, I have hereto aftxed myslgnaf ture in the presence of two witnesses.
